After 2 fruitless recent gull watches, tried Calvert BBOWT pre-roost again but too many overflying to sailing lake so moved to watch there. Eventually found THREE first-year ICELAND GULLS, all very pale, almost white plumaged birds. The first one was found at 6:05pm, then another 2 shortly after. Kept checking positions of the 3 and roost nicely spaced side on and settled and without doubt 3. First time ever found or seen 3 white winged gulls at same time. None of these three was the dark plumaged juvenile seen last week so definitely FOUR separate birds recently.
There was a month gap before these birds appeared so I reckon juvenile seen month or so ago was another. Roost intensively watched but that one not seen again, so reckon we've had FIVE birds.
